Recurring Rectocele/cystolcele is rated as "voiding disfunction". The actual condition is not what gets rated, but rather the symptoms. Here is the standard for voiding disfunction:
Voiding dysfunction:
Rate particular condition as urine leakage, frequency, or obstructed voiding.
Continual Urine Leakage, Post Surgical Urinary Diversion,
Urinary Incontinence, or Stress Incontinence:
Requiring the use of an appliance or the wearing of absorbent
materials which must be changed more than 4 times per day.......................... 60
Requiring the wearing of absorbent materials which must be
changed 2 to 4 times per day ......................................................................... 40
Requiring the wearing of absorbent materials which must be
changed less than 2 times per day .................................................................. 20
Urinary frequency:
Daytime voiding interval less than one hour, or; awakening to
void five or more times per night ........................................................................ 40
Daytime voiding interval between one and two hours, or;
awakening to void three to four times per night .................................................... 20
Daytime voiding interval between two and three hours, or;
awakening to void two times per night ................................................................. 10
Make sure you get documented in your medical records, how often you need to change absorbent materials. There is a catch 22 here, to find voiding disfunction unfitting, you must typically be catheterized, however with Recurring Rectocele/cystolcele, if you lift anything greater than 18#, do 3-5 second rushes etc., then you risk a tear or prolapse.
The rating process should take greater than 12-15 months in my opinion, just based upon the fact that you are most likely not medically stable.
To find PTSD after MST (the whole 9 yards..flashbacks, anxiety and panic attacks, nightmare, etc) unfitting, it is going to take some input from your commander with their non-medical assessment.
